How do I check EGR system wiring and connectors?
Getting the P0406 code on my 2002 F-150 5.4L V8. Before I start throwing parts at the problem, I want to test The EGR solenoid, DPFE sensor and EGR valve, as well as, the connectors and wiring for shorts. What's the best way to test for wiring or connector problems on the wiring harness itself?
